The primary PIDs (025) in the input stream are replaced with the secondary PID (125) for the clear packets (C). For the encrypted packets, the primary PID and secondary PID are retained, but the continuity counters are swapped. Thus, the stream of packets can now be properly decrypted and decoded without errors caused by loss of continuity using the secondary PID. Other methods for manipulation of the PIDs, e.g. mapping the PID (125) on the scrambled legacy packet to a NOP PID (all ones) or other PID value not decoded, and the continuity counters can also be used in embodiments consistent with the present invention.
